Concerns over geoengineering

Akshat RathiLeave a comment

The latest studies on solar geoengineering to tackle climate change are reinforcing the case for a global governance system and further study before deployment, as they show that the approach may have little effect on preventing rainfall changes in the tropics — and may even lead to widespread drought in Africa.

Several geoengineering initiatives plan to tackle climate change by cutting incoming sunlight, through methods such as spreading reflective aerosols in the stratosphere. But without also removing carbon dioxide from the atmosphere, such plans would fail to fully mitigate change in rainfall in the tropics, a study published in Nature Geoscience suggests.

Developing world science journalists lose out

The organising committee of the upcoming global gathering of science journalists has made sudden changes to the programme last month, cutting several sessions that focused on developing country issues and leaving journalists disappointed. In recent years the World Conference of Science Journalists has attracted up to half its attendees from the developing world. That seems unlikely now.

Uniting against cancer

Researchers from 15 developed and developing countries have called for better global coordination of research and prevention efforts against cancer, which kills 7.5 million people each year (about 15% of all deaths). A joint report published earlier this month (6 March) in Science Translational Medicine focuses on five areas that will help slash cancer cases and deaths: better and more coordinated registries, stronger action on prevention, easier and cheaper screening methods, better access to treatment, and the open exchange of research findings.
